LD7575PS Description

Short technical summary and product information.

The LD7575PS is a current-mode PWM controller designed for power-saving operations in AC/DC power applications. It features an integrated high-voltage startup circuit that directly supplies startup current from the bulk capacitor, providing a lossless startup solution.

Key features include non-audible-noise green mode control, under-voltage lockout (UVLO), leading-edge blanking (LEB) on the current sensing pin, internal slope compensation, and over-voltage protection (OVP) on the VCC pin. The device also offers over-load protection (OLP) and a driving capability of 500mA.

This controller is suitable for applications such as switching AC/DC adapters, battery chargers, open-frame switching power supplies, and LCD monitor/TV power supplies. It is available in both SOP-8 and DIP-8 packages, offering flexibility for different design requirements.

The LD7575PS supports programmable switching frequency, allowing designers to optimize performance. Its integrated functions minimize external component counts, contributing to a cost-effective and high-efficiency solution.
